Bitter blast of Arctic air sends temperatures plunging from Montana to Texas

Published Nov. 7, 2019 6:37 AM



Winterlike temperatures that pushed into the northern Plains through the middle of this week will continue charging south and east through the end of the week.
Cold air arrived in the northern Plains on Wednesday into Wednesday night as high pressure built into the region behind a large storm system moving into the Northeast. This system will bring the first taste of winter to parts of the Northeast along with periods of rain across the South.
Temperatures dropped into the single digits from Montana to the Dakotas and into northern Iowa throughout Wednesday night.
The normal low temperature for this region during the beginning of November is in the middle to upper 20s F.
The cold air did not stop in the northern Plains as near-freezing temperatures followed a cold front sinking south into Texas through Wednesday night.
In Amarillo, Texas, the high reached 72 F Wednesday afternoon before plummeting to 32 F early Thursday morning.
Residents in the panhandles of Texas and Oklahoma will have to take extra precautions during Thursday morning's commute. With temperatures near freezing, areas of drizzle can create icy spots and slippery travel conditions, especially on elevated surfaces.
Temperatures across Texas will be a tale of two seasons on Thursday.
"The cold front dividing Texas will bring about an incredible gradient in temperatures. Highs on the cold side of the front will easily be over 20 degrees lower than those on the other side, roughly 100 miles to the south," said AccuWeather Meteorologist Max Gawryla.
On Friday, the storm system in the Northeast will move off the East Coast and cold air will follow in its wake. However, snow will not end across the entire region as cold air moving over the Great Lakes will trigger lake-effect snow showers toward the end of the week.
High temperatures across parts of the Northeast will struggle to climb out of the 30s F, while interior locations of New England will be stuck in the 20s F.
"The low temperature could plunge to 25 F in Philadelphia on Saturday morning. It hasn't been this cold so early in the season there since 1976," Jesse Ferrell, AccuWeather meteorologist and social media manager, said. 
A stiff northwesterly wind will keep AccuWeather RealFeel® Temperatures about 10 to 20 degrees F lower across much of the region.
Normal high temperatures for the beginning of November range from the lower 40s F in northern Maine to the lower 60s F in the mid-Atlantic.

The Southeast will not be spared from this push of winterlike air as the chill is expected to penetrate into the Deep South.
"Afternoon high temperatures Friday will be 10-20 degrees below normal for early November across the Southeast, with widespread temperatures stuck in the 40s and 50s," stated AccuWeather Meteorologist Jake Sojda. "Even temperatures in communities along the Gulf coast will struggle into the 60s."
This will set up the potential for widespread frosts and freezes across the South Friday night. Readings for many communities away from the Gulf Coast will fall through the 30s Friday night, with some upper 20s even likely from Arkansas to northern Mississippi and northern Alabama into the Tennessee Valley.
Through the weekend, high pressure will shift to the east and winds across the Southeast will turn out of the south and southwest. This will allow for more mild conditions to return to the region.
While more comfortable air will return to the South through the end of the weekend and into the beginning of next week, another blast of Arctic air is forecast sink into the northern Plains.
Looking ahead to next week, a storm system may develop over the Plains and could bring another round of heavy rainfall to the southern Plains. The return of colder air to the central Plains can produce icy conditions near the dividing line of warm and cold air.
Another round of snow may be in the forecast for the Northeast as the storm is expected to track in that direction into the middle of the week.
Over the first couple of days of next week, most of the eastern two-thirds of nation could be 10-20 degrees below normal for mid-November.
"A widespread killing freeze is likely to end the growing season across much of the South early next week," said AccuWeather Senior Meteorologist Dan Kottlowski.
Low temperatures may fall below freezing all the way to the Gulf Coast, but the most intense cold will be in the northern Plains where temperatures may even fall below zero. Coupled with gusty winds, it will feel even colder across the region and time spent outside will need to be limited.
"While the extreme cold is expected to give way to a milder pattern to close out November, it may take until the third week of November to clear out the well below-normal temperatures from the northern Plains through the Great Lakes," AccuWeather Lead Long-Range Meteorologist Paul Pastelok said.
